Fast Times at Ridgemont High

I was flipping through TV stations and "Fast Times at Ridgemont High" was on. I watched the first couple minutes and noticed that one of the two kids trying to buy scalped Van Halen tickets was sporting a shirt that said WCSB. I didn't recognize it as one of ours. It was a creme colored long-sleeved shirt that had a color image on the back. Does that sound familiar to any of you? I could see Tony C sporting one of these back in 1982.

Here's the youtube link. Unfortunately, the image is mirrored (to avoid copyright issues) but the shirt is pretty clear. The scene in question is at 2:35.
